Labcorp Genetics (formerly Invitae), Labcorp RCV004580713 SCV005064737 pathogenic Hypoplastic enamel-onycholysis-hypohidrosis syndrome 2023-02-06 criteria provided, single submitter clinical testing Experimental studies and prediction algorithms are not available or were not evaluated, and the functional significance of this variant is currently unknown. A similar copy number variant has been observed in individual(s) with clinical features of MSX1-related conditions (Invitae). This variant results in the deletion of part of exon 2 (c.719_*95659del) of the MSX1 gene. While this is not anticipated to result in nonsense mediated decay, it is expected to disrupt the last 64 amino acid(s) of the MSX1 protein. This variant disrupts the C-terminus of the MSX1 protein. Other variant(s) that disrupt this region (p.Pro248Serfs*13, p.Phe251*, p.Ala282Argfs*21) have been observed in individuals with MSX1-related conditions (PMID: 27917906; Invitae). This suggests that this may be a clinically significant region of the protein. For these reasons, this variant has been classified as Pathogenic.
